Simon Metcalfe (also spelled Metcalf) (c. 1741 – 1794) was a British-born American surveyor and one of the first American maritime fur traders to visit the Pacific Northwest coast. As early visitors to the Hawaiian Islands in 1789, Metcalfe and his son Thomas Humphrey Metcalfe unwittingly provided Western military weapons and advisors for Kamehameha I, when two of their men and a ship and its armaments were captured. These helped the chief win strategic battles and unify the Hawaiian Islands. The son Thomas and most of his crew were killed about 1789-1790 in an attack by Hawaiian warriors, which the father never learned about. Simon Metcalfe later returned to the Pacific Northwest. He and all but one of his crew were killed in 1794 in an attack by Haida warriors who were allowed on the ship for trading. This was in what were then known as the Queen Charlotte Islands, now known as Haida Gwaii in present-day British Columbia, Canada. Life Simon Metcalfe was born in London, England, April 23, 1741. He was the son of George and Anne Metcalfe of Askrigg, Yorkshire. Due to a recent inheritance, they had moved to Shadwell, London, at the time of Simon's birth. Simon was baptized at 9 days old on May 1, 1741, at St. Pauls, Shadwell. In his early life he trained for a career at sea with the East India Company. He was married in Bolton-on-Swale, Yorkshire, on May 12, 1763, to Catherine Humphrey, daughter of Thomas and Elizabeth Humphrey of that town. Metcalfe said at that time that his address was Dowgate Street, London and that he was a merchant. His brother Bernard Metcalfe was his witness. He and Catherine Humphrey had at least nine children. About 1765, the family: Simon, Catherine and baby Elizabeth emigrated to the Province of New York, leaving son George in Yorkshire with Simon's brother Bernard, so that the boy could be educated. The Metcalfe family first settled in New York City, a major port. Metcalfe found employment as a surveyor and worked on the survey of the Fort Stanwix Treaty line in about 1769 in the western part of the province. He was promoted to Deputy Surveyor in the Province of New York by 1770. In 1771, Governor Dunmore of New York granted of land to Simon Metcalfe and his wife. This land was called Prattsburgh and is now part of Swanton and
